SPECIFICATION forming part of Letters Patent No. 626,117, dated May 30, 1899.

v Application filed July 8,1897. Serial No. 643,862. (No model.)

To @ZZ whom t may concern:

Be it known that I, FREDERICK WALTON, manufacturer, a citizen of England, residing at No. 114 I-Iolborn, in the city of London, England, have invented new and useful Improvements in Apparatus for Manufacturing Mosaic Floor-Cloth, (for which I have obtained Letters Patentin Great Britain, No. 198, dated January4, 1897; in Austria,No.219/47, dated January 22, 1897, and in France, No. 262,789, dated .Ianuary\4, 1897,) of which the following is a specification. 1

Apparatus for manufacturing mosaic floorcloth has been proposed wherein adrum having a numberof projecting pins had arranged around parts of its circumference several sets of cutting-cylinders and pressing-rollers to cut tesserze from traveling sheets of variouslycolored fl`oorcloth material to force the tessera; required for the pattern onto a backing fabric traveling around With the drum and to reject the tesserze not required and return them to be again converted into sheet. In Patent No. 523,610, granted to me July 24, 1894, I have shown and described one form of apparatus for accomplishing this work. My present invention relates to improvements in apparatus of this kind, especially in the construction of the cutting-cylinder, whereby I render it more efficient.

Each sheet of colored floor-cloth material passes between a cutting-cylinderand an iron pressing-roller by which the Whole sheet is cut into tesserze, filling all the spaces in the circumference of the cutting-cylinder. As this turns around the stems of the plates which form the botto ms of the tesserae spaces from which tesserae are to be rejected are acted upon by pins projecting from an internal eccentric cylinder, so as to push these tesserzc quite out of the spaces which they occupy, these tesserae being cleared away by an external revolving brush. As the cuttingcylinder continues to revolve until it comes to the line of contact with the main drum, all

the plates are pushed out by the passage of these stems or pins over an internal cylinder,

the tesserzc which remained in the spaces after passing the brush being thus pressed onto the backing fabric carried on the main drum. At a further part of the revolution of the cutting-cylinder all the plates are pushed by au internal cylinder acting on their stems and pins a little beyond the surface of the cutting-cylinder and meetA a revolving roller covered with plush or equivalent material vserved with a lubricant, such as petroleum spirit, the plates bein g thus lubricated, so that the sheet from adhering to the roller, its sur-l face is lubricated with paraffin-wax applied by a roller of felt or like material served with the lubricant.

, Figure 1 is an enlarged transverse section of the cutting-cylinder and part of the main drum, the pressing, brushing, and lubricating cylinders being indicated by dotted lines. Fig. 2 is a longitudinal section of the cuttingcylinder on the line 2 2 of Fig. 1, but on a smaller scale, with parts in elevation, showing at the one end the gearing for driving the cylinder A and at the other bearings foil the cylinders B, C, and D. Fig. 3 is a View of the right-hand end bearing of a cutting-cylinder provided with internal eccentric cylinders for moving the bottom plates of the tesserze Fig. 3'is a view of the left-hand end bearing of the same. Fig. 4 is a part section of the cutting-cylinder, showing one form of spring-stem for some nof the bottom plates; and Fig. 5 is a part section showing another form of the spring-stem for others of the bottom plates acted on by pushing-pins.

The cylinder A consists of an inner shell a and an outer shell a', in which are held the cutting-blades d2, arranged according to pattern all around the circumference. The cutting-cylinder is conveniently constructed in the following, which is awell-known, manner: A cylindrical shell of metal having thickness equal to that of the linoleum sheet to be cut and to the distance which the cutting-blades are to project is cut into tesserae according to the desired pattern, and these tesserze are placed in a concave mold, being a segment, preferably one-third, of the cylinder, circumscribng the blades when they project. The

IOO

. cutting-blades.

cutting-blades, each having part of its surface tinned, are set between the tesserre, their edges next the concave mold and their tinned parts projecting inward. The whole is then covered by a convex segmental cover, and then molten white-metal, which is fused at a comparatively low temperature-such, for instance, as type-metal-is poured into the space between the mold and cover, this metal becoming soldered to the tinned parts of the In this way are formed cyli ndrical segments of the white-m etal with the cutting-blades projecting from them in positions suited to form the desired pattern.` These'segments together form the outer shell a', being xed on the inner cylindrical shell a, the whole forming the cutting-cylinderA, which, being made as above described, has the pattern repeated three times around it. Each space inelosed by the cutting-blades has a central hole and also two or more smaller holes, all passing through both shells, and the plate a3, which forms the bott-om of each of those spaces from which tesserre are to be extruded as forming no part of the pattern, has attached to it a long stem a4, passing through both shells and projecting inwardly beyond the inner shell, as shown in Fig. 4c; but in this case there are no pushing-pins. The plate a5, on the other hand, which forms the bottom of each space containing tesserzc that are to form part of the pattern, has attached to it a short stem a, as shown in Fig. 5, and has arranged under it two or more pushingpins ai, which pass through the smaller holes of both shells, projecting inwardly beyond the inner shells. rlhe stems of both kinds a4 and a are Iitted to slide through bushes as, which are driven into holes of the outershell a with certain tightness, but not such as to p prevent them from being withdrawn for repairs or alterations when force is applied, and they are made with collars and have springs so arranged as to draw them inward. The pushing-pins a7, which are not attached to the bottom plates, are made with small collars at their heads to prevent them from falling out when they are brought by revolution of the cylinder A to an inverted position.

The cylinder A, which is open at both ends, is journaled its right end in a plate F and its left end in a plate F', both these plates being itted to slide in frames R, which also have sliding bearings for the shafts of the pressingroller P, the exact position of the axes'of the cylinders A and P being determined by ad-v in line with one of the long stems a, the meeting ends of the peg and the stem moving at the same rate. As different patterns require dierent arrangements of the stems a4 and pushing-pins a7 in the cylinder A, many of these different patterns can be provided for by corresponding arrangements ot` the pegs Z) on one cylinder Bv without requiring a sepa- The rate cylinder for each of these patterns. cylinder B is so geared to the cylinder A and the pegs b thereon are so arranged relatively to the stems a4, which have to be acted on by the pegs, as to fulfil the condition stated. It should be understood that one revolution of cylinder A cuts, say, three repetitions of one 1 pattern, and therefore if cylinder B be geared to cylinder A, so as to make three revolutions while the latter makes one, the pegs I will act on the stems a4 of each pattern.

Touching the cylinder A is mounted the pressing-cylinder P, preferably made ot' castiron. At the one side of A is mounted a revolving brush G, having on its axis a pulley g, driven from any convenient shaft of the machine by a belt. On the other side of A is mounted a lubricating-cylinder Il, which is clothed with plush or such like fabric and occasionally served with a little lubricant, such as petroleum spirit. K is the main drum of the machine, carrying on it the backing fabric L, through which project numerous pins fixed on the drum. The cylinder A is driven by teeth on the drum K gearing with the teeth e', so that the two circumferences move at equal speed. The revolving brush G is driven at a considerably more rapid speed, while the lubrieating-cylinder II is driven from the teeth e' on A at a surface speed a little greater than that of A.

The apparatus operates in the following manner: As the parts revolve in the direction of the arrows a sheet ot' colored floor-cloth material passing between the pressing-cylinder P and the cutting-cylinder A is entirely cut into tesserae, which occupy all the spaces of A that pass the line of contact of the two cylinders. All the longer stems a4 come in their turn to be acted on by the pegs l), pushing them outward and so extruding all the tesserae that are not required for the pattern, these being swept away by the brush G into a receptacle below. The tesserae occupying IOO IIC

the spaces which have bottom plates with the short stems a and under them the pushing pins a7 remain in those spaces, the pushingpins e7 being so arranged as not to be acted on by the pegs b; but when these pins come in contact wi th the cylinder C they are pushed outward, pressing the tesserfe on the backing L, on which they are heldby the pins of the drum K, projecting'through the backing. ,As

the front p ushing-pins al of each tesserae space are acted on by C a little before the hinder pins, the tesserae is pressed out of the space and onto the backing, rst, in a slightly-in- @lined attitude, heilig afterward flattened down on the backing when the hinder pushing-pins are acted on. The long stems a4 are also pressed outward by C, but as the spaces to which they belong are empty no effect is produced. The cylinder C has its su rfacc not quite in contact with the inner surface ot' A, so that the bottom plates areA not pushed out by C beyond the edges of the lcutting-blades of A. When the long stems a4 and pushingpins a7 come in contact with the cylinder D, which is in close contact with the interior of A, lthe bottom plates of the tesserac spaces are all pushed out, so that-their faces are a little beyond the edges of the cutting-blades and they are lubricated by contact with the cylinder H, the lubricationv of their surfaces preventing adhesion of the tesserze to them.
